Manchester United are eyeing West Ham whizkid Domingos Quina.

United boss Jose Mourinho is aware of Quina, having been in charge of Chelsea during the attacker's time with their academy.

Mourinho had representatives watch the midfielder feature for Portugal Under-19s against Spain, says ESPN.

And they would have been impressed with Quina's display after he bagged a goal in a 2-1 win.

The Hammers believed they landed a major coup when they signed Quina from rivals Chelsea.

Quina has yet to make his professional debut in the league for the Hammers and with a contract until the summer of 2019, United are taking a strong interest.
